Catalytic bio-oxidation of toxic Arsenite (As(III)) to Arsenate (As(V)) in a mixed culture of bacteria strains isolated from cow dip in Tzaneen (Limpopo Province South Africa) was investigated under anaerobic condition. Anaerobic bio-treatment of As(III) is thermodynamically feasible since facultative microbes perform a significant role in the biogeochemical cycling of (As) under anaerobic environment, while deriving energy for cell growth and metabolism. If this metalloid is not efficiently treated before disposal of wastewater, it could result in cancer even at very low concentrations. An experiment was conducted and conditions were enhanced by varying different parameters such as pH, carbon source, oxidation-reduction potential (OR...
